Advance Technology Cold Forming
In contrast to hot forming where the spring is coiled at an elevated temperature, springs of our series are made through the technique of cold forming (normal temperature forming at a non elevated temperature). By using a dedicated new-type coiling machine, deterioration of the material is prevented and advance performance is retained.

Made of SAE 9254 Steel 
Tested by over 500,000 times, compression inspection deformation less then 5% high strength sophisticated surface dealing, durability was highly improved.
